MOSCOW — A Russian lawyer for former National Security Agency contractor Edward Snowden says his client has applied to extend his stay in Russia.

Anatoly Kucherena said in comments quoted Wednesday by Russian news agencies that Snowden has applied to Russia’s migration authorities since his one-year permit is expiring at the end of July.

Snowden got stranded in a Moscow airport last year on his way from Hong Kong to Cuba, shortly after he revealed the NSA’s sprawling program tapping phones across the country. He received asylum in Russia, attracting the ire of the United States.
